Clone Wars

Is your hard disk making strange noises? Do you intend to make some major hardware changes? Maybe it’s high time to clone your disk. Four tools help Linux users and system administrators move their data and create one-to-one copies.

When doing so, it’s a good idea to approach dd with some respect. Although the tool is always ready to serve, carelessness can cause irreparable damage. If you don’t have good backups in this case, you can forget your data while you rebuild the system.
